Those flanges for RX7 turbo exhaust manifold application have an interesting color, shininess, and texture. I also notice that they welded cleanly, without any smut or "smoke". Do you know if they are they cast stainless steel? Do you think they are Nickel plated? Any theories on how they are manufactured?
I find it interesting that they look kind of rough in texture, as if they were sand cast, and yet at the same time also have kind of a "CNC machined look". I wonder if a CNC machined original part was pressed against mold sand material in preparation for the casting.
Your welds look great by the way.
Is your #12 cup a "large diameter" gas lens lens cup like this one and do you use it on all those stainless welds?
Also, what argon flow rate do you like to run through it? And finally, curious if you are using either solar flux or backpurging, and if so, how is that working. Thanks for sharing!
